• Configure MPLS LDP on PEs and Ps to establish LDP LSPs.
Configuring VPN instances
By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes, but
also routes between VPNs. This feature allows VPN instances to be used in network scenarios besides
MPLS L3VPNs.
All VPN instance configurations are performed on PEs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of its
associated site. A VPN instance might correspond to more than one VPN.
To create and configure a VPN instance:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create a VPN instance and
enter VPN instance view.
ip vpn-instance vpn-instance-name
By default, no VPN instance is
created.
3. Configure an RD for the VPN
instance. route-distinguisher
route-distinguisher
By default, no RD is specified.
4. (Optional.) Configure a
description for the VPN
instance.
description text
By default, no description is
configured for a VPN instance.
The description should contain the
VPN instance's related
information, such as its relationship
with a certain VPN.
5. (Optional.) Configure an ID
for the VPN instance.
vpn-id vpn-id
By default, no ID is configured for a
VPN instance.
Associating a VPN instance with an interface
After creating and configuring a VPN instance, associate the VPN instance with the interface connected
to the CE.
To associate a VPN instance with an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Associate a VPN instance
with the interface. ip binding vpn-instance
vpn-instance-name
By default, no VPN instance is
associated with an interface.
The ip binding vpn-instance
command clears the IP address of
the interface. Therefore,
re-configure an IP address for the
interface after configuring this
command.
